' 10 vention hasr for its object to provide a rim structure by'which a cushion tire having approximately the same peripherial dimension or diameter as a balloon type tire but being of a lesser depth than that of the balloon tire 1 maybe used on wheels that have been formerly equipped with the balloon tires.

It is a matter of commonlmowledge that wheels and their felloe bands which are pro vided for use on machines equipped with balloon tires are of a` smaller vdiameter than wheels that are to be equipped vwith tires not of the balloon type.

It is the chief object of the invention, as

before intimated to rovide some means l 7' Y v whereby it is possible to use the same-wheels and felloe bands as are standard equipment when furnished with balloon'tires where it is desired to Vuse cushion tires for example- Y and to do this without the necessity of malr- O .ing a. cushion tire of substantially the same cross section as theballoon tire.

In carrying out my invention I provide a rim unit composed of two pai-ts, one of which constituting la rim proper, receives the tire a while the other, constituting Atheiiller rim,

occupies the space between the rim proper and the felloe band of the wheel onWhich it is to be used, the two rim parts,'liowever, preferably, being permanently held together vas a single unit, the parts being so designed with respect one to the other and to the ielloe band as to reduce labor of substitutingthe cushion tire `for the balloon tire to the minimum.

rAnother object of the invention is to provide a rim unit for the purposes stated made entirely of rolled or sheet metal so as to reduce the cost of manufacture as well as to reduce the weight` of the parts to a minimum. In the drawings:

Figure 1 is a cross section illustrating one embodiment of my invention.

Figure 2 is a cross section illustrating a modification oi. the embodiment `shown in Figure 1.

Figure 3 is a cross section illustrating another embodiment of my invention.

Figure l is a similar cross section of a modiication of the embodiment shown in Figure 3.

Figure 5 is a cross section showing another modification of the embodiment shown in Figure 3.

Figure 6 is a cross section showing a further modilication of the embodiment shown in Figure 3. i

Y Figure 7 is a cross section illustrating still 'another embodiment of the invention which is a further modification of the embodiment illustrated in Figures 3 and 6.

In the drawings 1 designates a felloe band of a standard type, such for example as is used on Ford one-ton trucks equipped with balloon type tires. In the example given the outside diameter of the wheel with the elloe baud is approximately twenty inches and takes a tire of a size thirty inches by live inches. Now if it is desired to replace the pneumatic tire with a cushion tire, on a rim whose diameter is such as to fit on the felloe band 1, and yet maintain the outside diameter of the tire, it would be necessary to have a cushion tire of approximately thesa-me cross section as the pneumatic.' This not only would result in a greater increased cost for the cushion tire but Wouldvalso add unneces- Vsaryvweight to the car, since a cushion tire to sustain the same load as a given pneumatic tire may be made of a considerably lesser cross section than the pneumatic tire. Therefore, in order to enable a cushion tire T of normal cross section to be fitted to cars whose wheels are designed for balloon or other pneumatic tires of that general size, without the necessity of changing wheels or elloe 9 bands, I provide a two part rim unit which consists of the rim proper 7 on which the tire T is molded, and the filler rim which comprises a ring of channeled or tubular sheet metal secured to the rim proper in such having va iixed rim .formed of an' annular band and side Walls having rim. seats at their edges formed to'/ receive a pneumatic-tire ,.With" its demouiitable rim; into a cushiontired Wheel; the combination with the fixed rim,'of an adapter comprising a ychannelled f ring having a peripheral Wall'and side Walls,

vWalls of said iixed rim and apertured to receive securing bolts, and securing bolts passed through said fixed rim side Walls and said apertures to secure said Vadapter in place,

'and a cushion-tire rim carried by said adapter and secured to the same, the radius of .the adapter and the cushion tirerim being such that said radius plus the thickness of' the cushion tire Which is carried by the rim will be substantially the same as the radius of the pneumatic tiie and demountable rim it replaces, so that the adapter andits cushion rim may have substantially the same tread circumference as the replaced pneumatic tire and demountable rim.

2.1n a means for the vconversion of a pneumatic-tired Wheel of standard make having a fixedrim formed of an annular band and side Walls having rim seats at their dges formed to receive a pneuinatic-tire `with its demountable rim, into a cushion- Vtired Wheel; the combination with the fixed rim, ,of an adapter comprising a channelled ring having a peripheral Wall and side Walls, one of said side Walls having a flange to seat on one of the iixed rim side Wall flanges, the other side Wall of the adapter liav-ing a seat portion adapted to seat on the other rim seat of the fixed rim, means carried by said adapter and lapping over one of the side Walls of said fixed rim and apertured to receive securing bolts, and securing bolts passedvthrough said fixed rim side Walls and said apertures to secure said adapter in place, a cushion-tire rim carried by said adaptei'aiid secured to the same, said cushion-tire rim and said adapter having interengaging portions to hold the same against lateral motion relatively to one another, the radius of the adapter and the cushion tire rim being such that said radius plus the thickness of the cushion tire which is carried by the rim will be substantially the saine as v1the radius of the pneumatic tire and demountable rim it replaces, so that the f adapter and its cushion rim may have sub- Vmatic-tire Wheel of standard make having a cliannelled rim formed of an annular band and side walls having rim seats at their edges to receive a pneumatic-tire with its deinountable rim, into a cushion-tired Wheel; said means comprising an adapter consisting of a channelled ring having an outer peripheral Wall and side Walls, one of said Walls terminatingiii a flange to seat on one of the fixed rim seats, the other side wall having a laterally bent portion constituting a member adapted to seat on the other fixed rim seat, said last named side Wall of the adapter being further extended parallel to and over-lapping the adjacent side Wall of the fixed rim, and having bolt holes, securing .bolts passing through the side Walls 'of the fixed rim and through said bolt holes to secure the adapter in place, and a cushion-tire rim carried by the adapter, the radiusof the adapter and the cushion tire rim being such that said radius plus the thickness of theA Cushion tire which is carried by the rim Will be substantially the same as the radius of the pneumatic tire and deniountable rim it replaces, so that the adapter and its cushion rim may have substantially the same tread circumference as the replaced pneumatic tire Y and deiiiouiitable rim.
